q = m x C x ΔT
q = amount of heat energy gained or lost by substance = ?
m = mass of sample in grams = 100g of water
C = heat capacity (J/g•oC) = 4.18 J/g•oC for water
Tf = final temperature = 100oC
Ti = initial temperature = 0oC
ΔT = (Tf - Ti) = 100oC
q = 100g x 4.18 J/g•oC x 100oC = 40,000 J (41800 J rounded to one significant figure due to 100g and 100oC.)
water is not 1 dimensional so i don't think you meant 100 cm. You probably meant 100 cc which means cubic centimeters. 1 cubic centimeter = 1 mL The specific heat of water is defined as 1 calorie/mL/degree celsius. To raise 100 ccs 1 degree C you need 100 calories of energy.
Alot of heat .
because it has a great heat capacity
Realative humidity
1 calorie is needed to raise 1 g of water 1 °C. 350 * 22 = 7700 calories ■
Water is something that will be affected if you raise the temperature. When cooking, you may need to raise the temperature of water to a boil, in order to cook food.
The pressure of the atmosphere around the water determines the temperature at which it boils. Also, the presence of dissolved particles in the water will raise the boiling temperature.Dissolved solids (salt, sugar or anything else in there, This will raise the temperature). Pressure lower pressure means less temperature needed to boild the warer. (altitue on earth will do this cause higher altitudes means lower pressureDissolved solids (salt, sugar or anything else in there, This will raise the temperature).

A calorine is the amount of energy needed to raise the temperature of 1gram of water 1 degree celsius.

The amount of heat necessary to raise 1 gram of a substance by 1 degree Celsius is known as?
You need the amount of water, the temperature of the water, and the desired temperature.
1 calorie is defined as the amount of energy needed to raise the temperature of 1 gram of water by 1C, so... It takes 8.1 calories to raise your 8.1 grams by 1C, but you need to raise it 20C. 8.1*20=162. 162 calories is the answer you are looking for.
A calorie is the amount of energy that needed to raise the temperature of one gram of water one degree Celsius. The Joule is the SI unit for energy.
42 j

The metric unit is the calorie, which is the amount of heat needed to increase the temperature of a gram of pure water one degree Celsius. The standard unit is the British Thermal Unit (BTU), which is the amount of heat needed to raise the temperature of a pound of pure water one degree Fahrenheit.
The needed energy is 10 calories.
